25
What part of the brain measures blood levels of CO2
Medulla oblongata
26
What is the normal respiratory rate to pulse ratio
1 breath:4 pulse beats
27
When taking respirations what are you looking for
1. The rhythm if it is regular or irregular | 2. The depth (the amount of air that is inspired and expired)
28
What causes elevated respiratory rate
``` Excitement emotions fever lung disease pain shock hemorrhage drugs exercise nervousness ```
29
What can cause decreased respiratory rate
``` Sleep coma drugs pressure on the brain kidney disease ```
30
One inspiration and one expiration is equal to what
one respiration
31
NR for BP
less than 120 SBP | Less than 80 DBP
32
High BP (hypertension stage 1) range
140-159 SBP | 90-99 DBP
33
Prehypertension BP range
120-139 SBP | 80-89 DBP
34
High BP (hypertension stage 2)
160 & Higher SBP | 110 & Higher DBP
35
Hypertensive crisis
Higher than 180 SBP | Higher than 110 DBP
36
Blood pressure is measuring what?
the force of blood exerted on the peripheral arteries during the cardiac cycle
37
What is the name of the type of BP device used in health care today
sphygmomanometer Can be electric or manual, Manual is called Aneroid Manometer
38
What is the Korotkoff Sounds
blood flow sounds that healthcare providers observe while taking blood pressure with a sphygmomanometer over the brachial artery in the antecubital fossa. These sounds appear and disappear as the blood pressure cuff is inflated and deflated.
39
Phase 1 Korotkoff
K-1 (Phase 1): The appearance of the clear "tapping" sounds as the cuff is gradually deflated. The first clear "tapping" sound is defined as the systolic pressure.
40
Phase 2 Korotkoff
K-2 (Phase 2): The sounds in K-2 become softer and longer and are characterized by a swishing sound since the blood flow in the artery increases.
41
Phase 3 Korotkoff
K-3 (Phase 3): The sounds become crisper and louder in K-3 which is similar to the sounds heard in K-1.
42
Phase 4 Korotkoff
K-4 (Phase 4): As the blood flow starts to become less turbulent in the artery, the sounds in K-4 are muffled and softer. Some professionals record diastolic during Phase 4 and Phase 5
43
Phase 5 Korotkoff
K-5 (Phase 5): In K-5, the sounds disappear completely since the blood flow through the artery has returned to normal. The last audible sound is defined as the diastolic pressure.
44
If hypertension goes untreated it will cause damage to what
the heart, kidneys, eyes, and arteries
45
it takes how many dr visits to diagnose hypertension
3 separate visits
46
How many types of HTN (hypertension)
4 types 1. Primary 2. Secondary 3. Benign 4. Malignant
47
Primary HTN
No apparent cause or cure, most common type, tx is life long
48
Secondary HTN
results of another medical condition such as pregnancy, renal disease, obesity. When underlying problem resolved BP returns to normal
49
Benign HTN
HTN that has a slow progression, most primary is benign
50
Malignant HTN
Very rare, progresses rapidly, damages cardiovascular system
51
HT (hypotension) NR
Usually below 90/60 seen with hemorrhage, shock, CNS (central nervous system) disorders and treatabe
52
Pulse oximetry
Can measure the O2 saturation continuously and accurately to detect a drop in saturation before a Pt becomes cyanotic
53
Cyanosis
a bluish discoloration of the skin resulting from poor circulation or inadequate oxygenation of the blood.
54
Dyspnea
difficulty breathing a s/s of a decline in O2 saturation
55
Orthopnea
in ability to breath in any position other than sitting straight up or standing
56
Diaphoresis
extreme perspiration
57
What is a pulse omimetry
it measures both )w saturation and the pulse rate.
58
What is a normal O2 saturation level
95%-100% if lower alert the nurse or MD
59
What is O2 saturation mean
the bodies hemoglobin molecules are bound to an O2 molecules and if every hemoglobin were attached to an O2 then the body would be at 100% saturation
60
If O2 saturation is below 90% what can happen
it could be life threatening situation
61
Can you apply an oximetry to the same hand of an arm that has a pressure cuff on it
NO
62
Dysrhythmias is a oximetry limitation becasue
the abnormal heart rhythms (dysrhythmias) can cause inadequate perfusion and lead to falsely decreased O2 stats.
63
Perfusion
the process of oxygenated blood being delivered to the tissues of the body. ... Perfusion of the body's tissue occurs during Systole. The chambers contract and the oxygenated blood is forced into the arteries. These arteries carry the blood to the tissues where the oxygen is removed from the blood.
64
Oximetry can have skewed results from what
Nail polish acrylic nails intravenous dyes (especially dark colors)
